Hydroxypropyl starch ether(HPS) imhando yesitarch ether inotorwa kubva kune yakasikwa starch, sechibage, mbatatisi, kana tapioca starch. Inoshandiswa zvakanyanya muindasitiri yekuvaka sekuwedzera mune dzakasiyana siyana zvekuvaka nekuda kweiyo yakasarudzika zvivakwa. Heano tarisa pane basa rehydroxypropyl starch ether mukuvaka:

1. Kuchengeta Mvura: HPS inoshanda sechinhu chinochengeta mvura muzvinhu zvekuvakisa, semadhaka ane simende, magiroti, uye zvigadzirwa zvegypsum. Inobatsira kuvandudza kushanda uye kuenderana kwezvinhu izvi nekudzikisa kurasikirwa kwemvura panguva yekusanganisa, kushandisa, uye kurapa. Iyi yakawedzerwa nguva yekuchengetedza mvura inobvumira hydration iri nani yemabhinda esimende, zvichikonzera kuvandudzwa kwesimba uye kusimba kwechigadzirwa chekupedzisira.
2. Kuwedzeredzwa Kushanda: HPS inovandudza kushanda uye kubata maitiro ezvivakwa zvekuvaka. Nekuwedzera kubatana uye purasitiki yemasanganiswa esimende, inoita kuti zvive nyore kusanganisa, kupomba, uye kushandiswa kwedhaka uye grouts. Uku kukwidziridzwa kushanda kunogonesa kutsetseka kwepamusoro kupedzisa uye kurongeka kwakanyatso kurongeka kwezvinhu zvekuvaka.
3. Yakavandudzwa Kunamatira: HPS inogona kuwedzera kunamatira pakati pezvivakwa zvekuvaka uye substrates. Kana yawedzerwa kumatairi anonamira, marender, kana plaster coating, inosimudzira zvirinani kubatana kune akasiyana siyana, kusanganisira kongiri, masonry, huni, uye gypsum board. Kuvandudzwa kwekunamatira kunovimbisa chisungo chakasimba uye chakasimba, kuderedza njodzi ye delamination kana kutadza nekufamba kwenguva.
4. Yakaderedzwa Sagging uye Slump: HPS inoita senge rheology modifier, inobatsira kudzora kuyerera uye kuenderana kwezvinhu zvekuvaka. Nekupa hunhu hwekuveura-kutetepa, zvinoderedza kudonha uye kudonha mukumira kana pamusoro pemaapplication, senge kuisirwa mataira, render, uye stucco coatings. Iyi thixotropic pfuma inochengetedza zvirinani dimensional kugadzikana uye inodzivirira deformation panguva yekushandisa uye kurapa.
5. Crack Prevention: HPS inogona kubatsira mukudzikisa chiitiko chekutsemuka mune simende zvinhu. Nekusimudzira kubatana uye kusimba kwesimba redhaka uye kongiri musanganiswa, zvinobatsira kuderedza kuputika kwekuputika uye kuremara kwepasi. Izvi zvinonyanya kukosha mumashandisirwo apo kuvimbika kwechimiro uye kusimba kwakakosha, senge mukugadzirisa kongiri uye kupera kwekushongedza.
6. Kuenderana neZviwedzerwa: HPS inowirirana nehuwandu hwakawanda hwezvimwe zvinowedzera zvinowanzoshandiswa mukuvaka zvinhu, zvakadai semhepo-entraining agents, plasticizers, uye mineral admixtures. Inogona kuiswa nyore nyore mukugadzirisa pasina kukanganisa kushanda kana zvinhu zvezvimwe zvikamu, kuve nechokwadi chekugadzirisa kugadzikana uye kusagadzikana.
7. Kusagadzikana Kwezvakatipoteredza: HPS inotorwa kubva kune inogona kudzokororwa uye biodegradable starch masosi, zvichiita kuti ive sarudzo ine hushamwari yezvakatipoteredza zvekushandisa zvekuvaka. Inogona kubatsira kudzikisa tsoka yezvakatipoteredza yemapurojekiti ekuvaka nekutsiva madhizaini ekugadzira nemamwe akasarudzika.

hydroxypropyl starch ether inoita basa rakakosha mukuvandudza kushanda, kushanda, uye kusimba kwezvinhu zvekuvaka. Kuchengetwa kwayo kwemvura, kukwidziridzwa kwekunamira, rheology control, uye kuputika kwekudzivirira zvivakwa kunoita kuti ive yekuwedzera yakakosha mumhando dzakasiyana dzekuvaka, zvichibatsira kumhando uye hupenyu hurefu hwezvivakwa zvakavakwa.
